THE HABITAT OF APHREDODERUS SAYAXUS IX

The first published note of the occurrence of the pirate 

 perch {Aphrcdoderus sayanus) in Michigan was made by 

 Bollman/ who recorded "two specimens taken in a small 

 brook which flows into Howard Lake." Although the several 

 small streams (only a few rods in length) which are tributary 

 to this lake have often been examined by the writer, they 

 have never yielded Aphredoderus. Encalia i}ico}ista)is, in 

 contrast, lives here in great abundance. 



Aphredoderus sayanus is, however, a common fish in two 

 streams flowing from the north into Black Lake, immediately 

 north of Howard Lake. The larger (more easterly) of these 

 two brooks rises little more than two miles from the lake in 

 a level oak country. Although but a small ditch for most of 

 its length, in its last third of a mile it expands into a gentle
